EDITED: I'm probably misinterpreting but I assuming the spry effect resets the visibility from hidden to visible. So unless you edit the javascript to reset dispaly, the object still has the display:none property. Any reason you can't just hide it using visibility: hidden?

If I use visibility:hidden, the content does not appear but blank space appears as it is in the page flow. If I set display:none, the content is removed from the page flow. I will try your suggestion on editing the file.
